  • Data sources and NSTableView

    - by lampShade
    I know that table sources need a data source to hold the data that the tableview will display. Lets' say that I'm going to make my AppController be the data source of my tableview and that I make the connection in interface builder. My question is since my actual data is going to be stored in an array,let's call it myArray, when I set the data source in code should I do this [tableView setDataSource:myArray]; or this [tableView setDataSource:self]; I'm confused about this. setting the data source with the keyword "self" would set it to the AppController if I'm not mistaken.

  • VB.NET class inherits a base class and implements an interface issue (works in C#)

    - by 300 baud
    I am trying to create a class in VB.NET which inherits a base abstract class and also implements an interface. The interface declares a string property called Description. The base class contains a string property called Description. The main class inherits the base class and implements the interface. The existence of the Description property in the base class fulfills the interface requirements. This works fine in C# but causes issues in VB.NET. First, here is an example of the C# code which works: public interface IFoo { string Description { get; set; } } public abstract class FooBase { public string Description { get; set; } } public class MyFoo : FooBase, IFoo { } Now here is the VB.NET version which gives a compiler error: Public Interface IFoo Property Description() As String End Interface Public MustInherit Class FooBase Private _Description As String Public Property Description() As String Get Return _Description End Get Set(ByVal value As String) _Description = value End Set End Property End Class Public Class MyFoo Inherits FooBase Implements IFoo End Class If I make the base class (FooBase) implement the interface and add the Implements IFoo.Description to the property all is good, but I do not want the base class to implement the interface. The compiler error is: Class 'MyFoo' must implement 'Property Description() As String' for interface 'IFoo'. Implementing property must have matching 'ReadOnly' or 'WriteOnly' specifiers. Can VB.NET not handle this, or do I need to change my syntax somewhere to get this to work?

  • What is the process of turning HTML into Postscript programmatically

    - by Dean
    I am trying to understand what the process is of turning HTML into a PDF/Postscript programmatically All Google searches turn up libraries to do this, but I am more interested in the actual process required. I know you could just set up a Postscript printer and print directly to that, but some of these libraries appear to create the PDF on the fly to allow previews etc. has anyone had any experience in this, or can provide any guidance?

  • Transform PDF to HTML, keep layout

    - by Tgr
    What methods are there to transform a PDF to HTML? It could be anything - online service, software, library. (Opensource preferred. In the last case, php or python would be preferred.) It has to keep the original layout (including page numbers, footnotes and such), keep the images (combining them to one single background image per page is acceptable) and keep the links. It should preferably output valid XHTML and clean up PDF features such as ligatures, but if there is some post-processing required, I can live with that. Something with a clean, relatively semantic HTML output would be great. The closest one I found was zamzar.org, but it choked on links. (Also, the HTML output is an ugly heap of absolutely positioned divs and needs post-processing because of encoding problems.)

  • Java text to applet converter ... is there such a thing?

    - by Jahkr
    Let's say you have this program: public class sample public static void main(String args[]) { System.out.println("Hello world!"); } } ... is there a converter that will turn it into this: import java.applet.Applet; import javax.swing.*; public class sample extends JApplet { public static JTextArea area; public void init() { area = new JTextArea(); add(area); area.append("Hello world!"); } } I mean, I can do it by hand... but it would take some time.

  • Convert byte array to understandable String

    - by Ender
    I have a program that handles byte arrays in Java, and now I would like to write this into a XML file. However, I am unsure as to how I can convert the following byte array into a sensible String to write to a file. Assuming that it was Unicode characters I attempted the following code: String temp = new String(encodedBytes, "UTF-8"); Only to have the debugger show that the encodedBytes contain "\ufffd\ufffd ^\ufffd\ufffd-m\ufffd\ufffd\/ufffd \ufffd\ufffdIA\ufffd\ufffd". The String should contain a hash in alphanumerical format. How would I turn the above String into a sensible String for output?

  • Valid signed Hex to long function

    - by Ben
    I am trying to convert a 24bit Hexadecimal string (6 characters) signed in two's complement to a long int in C. This is the function I have come up with: long int hex2li (char string[]) { char *pEnd; long int result = strtol (string, &pEnd, 16); if (strcmp (pEnd, "") == 0) { if (toupper (string[0]) == 'F') { return result - 16777216; } else { return result; } } return LONG_MIN; } Is it valid? Is there a better way of doing this?

  • Google Visualization Annotated Time Line, removing data points.

    - by Vitaly Babiy
    I am trying to build a graph that will change resolution depending on how far you are zoomed in. Here is what it looks like when you are complete zoomed out. So this looks good so when I zoom in I get a higher resolution data and my graph looks like this: The problem is when I zoom out the higher resolution data does not get cleared out of the graph: The tables below the graphs are table display what is in the DataTable. This is what drawing code looks like. var g_graph = new google.visualization.AnnotatedTimeLine(document.getElementById('graph_div_json')); var table = new google.visualization.Table(document.getElementById('table_div_json')); function handleQueryResponse(response){ log("Drawing graph") var data = response.getDataTable() g_graph.draw(data, {allowRedraw:true, thickness:2, fill:50, scaleType:'maximized'}) table.draw(data, {allowRedraw:true}) } I am try to find a way for it to only displaying the data that is in the DataTable. I have tried removing the allowRedraw flag but then it breaks the zooming operation. Any help would be greatly appreciated. Thanks

  • Convert String value format of YYYYMMDDHHMMSS to C# DateTime

    - by SARAVAN
    I have a need to convert a string value in the form "YYYYMMDDHHMMSS" to a DateTime. But not sure on how, may be a DateTime.Tryparse can be used to make this happen. Or is there any other way to do it. I can do this using some string operations to take "YYYYMMDD" alone, convert to a datetime and then add HH, MM, SS separately to that DateTime. But is there any DateTime.TryParse() methods that I can use in one line to convert a "YYYYMMDDHHMMSS" format string value to a DateTime value?

  • Why isnt my data persisting with nskeyedarchiver?

    - by aking63
    Im just working on what should be the "finishing touches" of my first iPhone game. For some reason, when I save with NSKeyedArchiver/Unarchiver, the data seems to load once and then gets lost or something. Here's what I've been able to deduce: When I save in this viewController, pop to the previous one, and then push back into this one, the data is saved and prints as I want it to. But when I save in this viewController, then push a new one and pop back into this one, the data is lost. Any idea why this might be happening? Do I have this set up all wrong? I copied it from a book months ago. Here's the methods I use to save and load. - (void) saveGameData { NSLog(@"LS:saveGameData"); // SAVE DATA IMMEDIATELY NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *gameStatePath = [documentsDirectory stringByAppendingPathComponent:@"gameState.dat"]; NSMutableData *gameSave= [NSMutableData data]; NSKeyedArchiver *encoder = [[NSKeyedArchiver alloc] initForWritingWithMutableData:gameSave]; [encoder encodeObject:categoryLockStateArray forKey:kCategoryLockStateArray]; [encoder encodeObject:self.levelsPlist forKey:@"levelsPlist"]; [encoder finishEncoding]; [gameSave writeToFile:gameStatePath atomically:YES]; NSLog(@"encoded catLockState:%@",categoryLockStateArray); } - (void) loadGameData { NSLog(@"loadGameData"); // If there is a saved file, perform the load NSMutableData *gameData = [NSData dataWithContentsOfFile:[[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"gameState.dat"]]; // LOAD GAME DATA if (gameData) { NSLog(@"-Loaded Game Data-"); NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:gameData]; self.levelsPlist = [unarchiver decodeObjectForKey:@"levelsPlist"]; categoryLockStateArray = [unarchiver decodeObjectForKey:kCategoryLockStateArray]; NSLog(@"decoded catLockState:%@",categoryLockStateArray); } // CREATE GAME DATA else { NSLog(@"-Created Game Data-"); self.levelsPlist = [[NSMutableDictionary alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:kLevelsPlist ofType:@"plist"]]; } if (!categoryLockStateArray) { NSLog(@"-Created categoryLockStateArray-"); categoryLockStateArray = [[NSMutableArray alloc] initWithCapacity:[[self.levelsPlist allKeys] count]]; for (int i=0; i<[[self.levelsPlist allKeys] count]; i++) { [categoryLockStateArray insertObject:[NSNumber numberWithBool:FALSE] atIndex:i]; } } // set the properties of the categories self.categoryNames = [self.levelsPlist allKeys]; NUM_CATEGORIES = [self.categoryNames count]; thisCatCopy = [[NSMutableDictionary alloc] initWithDictionary:[[levelsPlist objectForKey:[self.categoryNames objectAtIndex:pageControl.currentPage]] mutableCopy]]; NUM_FINISHED = [[thisCatCopy objectForKey:kNumLevelsBeatenInCategory] intValue]; }

  • How to use the Bass library to convert audio to another format (using C#)

    - by Siemsen
    Good day everyone and happy holidays. I'm trying to create a "simple" program that allows me to create a list of video files (Youtube video's to be precise) that are then run through by my program and converted any given format to pure MP3 audio. For this purpose I'm trying to use the BASS.dll and well it isn't going so well. I was wondering if anyone has used BASS to convert from one audio format to another? Or is there another library better suited for this?

  • Php mail pulling form data from previous page

    - by Mark
    So I have a form being filled out on one php like so: <p> <label for="first_name">First Name: </label> <input type="text" size="30" name="first_name" id="first_name"/> </p> <p> <label for="last_name"> Last Name:</label> <input type="text" size="30" name="last_name" id="last_name"/> </p> <p> <label for="address_street">Street:</label> <input type="text" size="30" name="address_street" id="address_street"/> </p> <p> <label for="address_city">City:</label> <input type="text" size="30" name="address_city" id="address_city"/> </p> <p> <label for="address_state">State/Province:</label> <input type="text" size="30" name="address_state" id="address_state"/> </p> <p> <label for="email">Your e-mail: </label> <input type="text" size="30" name="email" id="email"/> </p> <p> <label for="phone">Your phone number: </label> <input type="text" size="30" name="phone" id="phone"/> </p> This is on one php page.

  • Creating an Order Column for encrypted data

    - by SetiSeeker
    I am saving encrypted data to a database. Is there a way I can create a "hashcode" or fingerprint or checksum of the plain text data, that if I sort / order by on the "hashcode" the order would be the same as if I had saved the plain text data and perform the same sort / order by operation on it? I basically need a SOUNDEX() type function that will give me a value that will maintain the order of the plain text data. I would then save both encrypted data and the "hashcode" and when querying the data order by the "hashcode" field. I need to perform this in the application and preferably not in the SQL DB if at all possible. I am using Entity Framework and SQL 2008 and C# 4.0.

  • using jquery to load data from mysql database

    - by Ieyasu Sawada
    I'm currently using jquery's ajax feature or whatever they call it. To load data from mysql database. Its working fine, but one of the built in features of this one is to load all the data which is on the database when you press on backspace and there's no character left on the text box. Here's my query: SELECT * FROM prod_table WHERE QTYHAND>0 AND PRODUCT LIKE '$prod%' OR P_DESC LIKE '$desc%' OR CATEGORY LIKE '$cat%' As you can see I only want to load the products which has greater than 0 quantity on hand. I'm using this code to communicate to the php file which has the query on it: $('#inp').keyup(function(){ var inpval=$('#inp').val(); $.ajax({ type: 'POST', data: ({p : inpval}), url: 'querys.php', success: function(data) { $('.result').html(data); } }); }); Is it possible to also filter the data that it outputs so that when I press on backspace and there's no character left. The only products that's going to display are those with greater than 0 quantity?

  • Convert VB6 Randomize to C#

    - by Thomas G. Mayfield
    I'm writing a C# frontend to a legacy database that uses VB6 Rnd() and Randomize() methods for user password encryption. The encryption function is very simplistic and really not all that secure, but it's what all current passwords are stored with. What I'd like to be able to do is authenticate legacy users from a C# application. I can write new encryption (or preferably hashing) code for VB6 so that all future users have a more secure password, and that can be duplicated in C#. But I don't want to require current users to have had their password reset before they can use the new frontend. Is there any way I can reimplement that algorithm in C# so that it produces identical results to the legacy VB6 code?

  • Function that converts hex color values to an approximate color name?

    - by dclowd9901
    I don't suppose anyone knows of a function (PHP, preferably) that can take a hex color code and give an approximate color name for that hex value. I don't need a solution with 100s of colors. Even if it just amounted to the colors white, black, red, green blue, brown orange and yellow, I'd be pretty well in shape. If you don't know of an existing resource, does anyone know of a good way to approach this problem? Thanks in advance for the help.
